A LABELING MACHINE.

Application led November 2l,` 192i. Serial No. 516,550.

To al? al1/fiom it may concern.'

Be it known that l, Hongrie GATES, a cit-izen of the United States, residing at Worcesi ter, in the county of Worcester and State oi Massachusetts, have invented a. new and useful Labeling Machine, of which the following is a specication.

This invention relates to a labeling machine of the type in which the labels are tal'ren from a label holder intermittently by continuous rotary motion of a gumming cylinder or other gum 'applying device and kept in motion edgewise along a path until they come into Contact with. the articles'to be labelled which are also moving along a converging path so that the labels can be rolled down on the surface of the article in exactly the desired position while the labels and receptacle are travelling along together.

The principal objects of the invention are to !'irovidc a label holder withrmeans for positively holding the front of lthe labels whenever the label holder is not in position for applying the label to the gumming device; to provide means foroperating this holder intermittently in sucha way yas to periodically bring the front label of a bundle in the label holder into Contact with the gumming` device and then remove it therefrom to allow a. label to be taken off; to in'ovide a device for holding the tops of the labels in position, which in its preferred form is operated by gravity and; positively limited as to its forwardvmotion; to provide a combination of the above mentioned devices in such a way as to eliminatethe necessity of having fingers of any material length at the bottom of the label holderl for preventing the labels from being accidentally dislodged from it there; to provide a follower for the labels actuated yieldingly, preferably by gravity, and guides therefor as well as a clutch device for preventing the follower moving forward and pressing on.v

the labels in the holder when the label holder is in delivering position and to allow a yieldingl pressure of the labels against the drum but which will not prevent the follower from being forced back by the drum or even drawn back by hand at any time; to construct one side ot' the label holder in `such a way that it can be turned up into a position to permit `the operator to get at the labels from the side to introduce a bundle of labels or to take them out; to pro-.

vide a novel ine-ans for reciprocating the label holder toward and from the gumming cylinder automatically; to provide such a label holder operating mechanism in combination with the means for driving the above mentioned gumming cylinder so that they will work together, and to provide means whereby the label holder can be disconnected conveniently so that the rest of the machine can be operated without it for trying it out; to provide an improved gumy ming cylinder for applying the gum `to the labels and at the same time `withdrawing the labels from the holder, of such a nature as to avoid the application of too much gum to the labels and to securea continuous motion of each label from the `time it leaves the label holder until it is applied to the article; to provide a simple and inexpensive means for insuring the travel of the label edgewise along with the drum throughout the path of travel and positively guide the front 'end'of the label between the contact roll and the gumming` cylinder; to provide means for regulating and distributing the gum evenly over-the surface of the cylinder before applying the labels; to provide eiiicient means, easily detachable and replaceable, for .releasing the label from the drum yandfaltering its course'so as to bring it'intocontact with the article to be labelled; to provide convenient means forrolling `the label on the articlev and an effective device for preventing the article from Ajumping` `up atthe rear when the pressure of the labeling` roll is applied to it at the front end; to provide anirnprovedv gum boX for continuously applying gum to the gumming cylinder in a uniform manner, to so arrange the gum box that whether full ornearly empty it will always deliver by gravity substantially the same amount of adhesive and do it in a uniform manner; to providev a conveyor for the articles to be labelledL which can be adjusted conveniently Vand timed so as to bring the receptacles into positions for receiving alabel Just as fast as the labels are delivered; to provide improved arrangements for driving` the `conveyor and for adjusting its Widthand means for cushioningthe conveyor so that the apn plication of a label can be conducted on a l yieldingly mounted support; andto provide improvements in the means for guiding the article to be labelled on the conveyor by which the article is held out of position toy ll U all

I have `shown the invention in a forni in which aframe 1() `is employed resting on legs 11 and supporting the parts of this machine. -Tlie driving shaft 12 is driven byr a belt Ona pulley 13 or in any other desired manner. On this shaft are fixed two cams 1li and 15 operating two rolls 16 and 17 lThese two rolls are rotatably mounted onstudsiixed to a yoke 18. This yoke has an elongated opening 19 therethrough for the shaft 12` to pass through. The rotationof the shaft causes the yoke to be moved in one direction by 'one cam and in the IUI) oppositefdirection by the other so it has a.

reciprocating motion. At one end the yoke is pivoted to the top of an upright pivoted ar1n20 and at the other end it is provided with a vertical pivot 21 on which is mount ed a handle'22 lto swing on the axis of this pin. This handle has a passage through it and ythrough this passage extends a horizontal connecting and pivot pin .3 having a loose head 2li locatedy in a slot `25 in the handle 22.` This pin there-fore moves back and forth horizontally with the handle. Itl passes into-a bushing 26 which passes through the end vof an upright pivoted arm 27 and the end of the yoke. 18. The arms .20 .and 27 are similarbut lo 'ated atopposite ends of the machine.

Beyond' the yoke the pin 23 when in operatiom-fits in a perforation in an upright-pivoted arni constituting one side of yoke 28. This pin therefore normally pivotally connects the yokef 18 with the arms or levers' 27 and 28 but it can be withdrawn into the bushing 26-soV as t0 disconnect the arm of the yoke 28 fromv the other parts. There isa yoke 29 at the other end of t-he machine which corresponds `with theyoke 28 and is inlll tended to keep parallel with it. These yokes are pivoted at two points 36 at the ends or' the` machine. j

The arlns or levers 2T and 20 are also pivoted at the same points and they extend down below and are shown as connected across the bottom by 'a longitudinal har 31 pivoted to theirl lower ends. Tt may be stated here that although the arms 26 and 29 move together they are not pivoted together or otherwise connected at the top of the arm 20 and that end ot the yoke 18. In other affords, there is no connection at that end corresponding with the pin 23.

The reciprocation of the yoke 18 causes the two arms 20 and 2T and the two yokes 28 and f2.9 to swing on their pivots uniformly and with a parallel motion.

Each yoke 28 and constitutes a lever which is part of a swinging trame at the ends oit' the machine which is in the form of a rectangle having` bottom and top cross bars. At the top a pair ot longitudinal rails are pivoted to the yokes 26 and 29 on horizontal axes for transmitting the rocking motion to the yoke 29 as parallel motion.y Fixed with respect to these rails 32 are side j frames 33 of skeleton form which constitute means tor supporting the label holder or hopper. They support a right and left hand screw `3e extending across the iront. This is operated by a head 35 at one end and carries a pair of nuts 36 from which depend the two integral sides 37 ot the label holder. These sides can be moved toward and from each other to adjustthe Width of the holder by turning this screw When turned to the proper position it is held by a check nut it' desired.

Carried by the yoke 28 is a cross bar 38 and carried by the side piece B7 on the right side is a pivoted hook 39. This side piece can be swung up to the dotted line position shown in Fig; 13 and the hook supported by the cross bar so that the side piece is out of the Way and a bundle of labels la can be inserted, Withdrawn or adjusted. Theyrest on a bottom plate l0 which constitutes the bottom ot the label holder. Thebottom plate is supported by cross pieces l1 carried by the frames 33 and has a small front lip 104.

Projecting down from each of the sides 37 is an integral arm l2 which has a cam surface a?) on the bottom adapted, when the labelholder is moved forward, to engage a cross vrod all freely rotatable on stationary studs on the `yoke 2S near its point of pivotal support. This lifts the sides 37 slightly as the'label holder is moved forward. This moves their lower front ends back so `that they will not engage the gumming cylinder 100. This position of the parts is shown in Fig. 6.

The tops ot the yokes 28 and 29-carry guide rollersA 50. vl have shown these guideV rollers as arranged in pairs, each roller being of grooved loi-1n to carry between them a follower beam in the `forni oit a slide 5l. This beam is orf rectangular erossssection and 4extends from one end of the machine to the other. at the center. lt rests on the tiro bottom'rolls 50 and is guided by the top ones. .at the frontend of `the machine a flexible oord or sable 52 is connected with this follower beam and extends forward over a pulley 53. lt depends trom that and has a weight 5e upon it w iich normally but yield ingly forces the follower beam lorwsujfjl.`

The rear end ot the follower beam is prt vided with a follower frame which elo tends downand 'torwardly aud is provided at its lower end with a plate 56 which con*- stitutes the rear end of the label holder. This plateis connected with the Vtollower 'trame three studs 517 mounted on the rear ot the plate. Two of these studs exiltend into unrestricted openings in the fololi which guides a roll 63 or Gain' accordsy ance with the motion of the label holder.` These rolls are'mounted on studs, one stud being xed on a lever 65 which is duplicated on the other side andprovided at the top with a cross bar constituting a label guard 66. This pair of levers and guard constitute a rigid frame pivoted near its centeron two arms. 67, onthe end ofone yof which is located the roll 6a.' These arms are lixed rigidly together by a cross bar to kconstitute a trame which is pivoted by studs 67A to the label holder -irame 33; As the label trarne moves back and forth withv the yoke 18 the roll 64 is caused to rise in the cam slot 62 and thus swing the frame 67. lWhen it reaches nearly the end ot its stroke the roll 6apasses into a horizontal extension of the slot 62 and positively holds the guard 66 up. During' thewhole ot this motion the roll 63I is guided in the slot 61 from the position shown in Fig. 2 to that shown in Figs. 1 and 18 and `bark again. .This `action is to swingthe guard in at the front ot the label holder to engage the 'liront label and hold the label back in the holder until the label lill! holder moves up into position for a label to il u 11l of the label holder.

Alo

the frames 33 which carry itj is directlyforward and back.

Pivotally mounted on studs carried by the side frames 33 is a vclutch frame 7 This has at the bottom tivo adjustable screws 79, adapted to engage the arms of the yoke when the clutch frame moves back. This swings this frame, which is in the form of a lever, back at the top. i spring 723 engaging the screw 342 holds the frame forward at the top and yieldingly presses the `heads of the screws 72 against the forward edges of the yoke 2S when it permitted to do so. 'itfthe top. this clutch frame is provided with a clutch '7L/i in the form of a pivoted plate having a fiat upper edge that engages the bottom edge of the follower beam.` lts action' is such that when the screw 72 is pressed forward the clutch will be moved back out of operative position but at other times it engages the follower beam in such a way as to permit of its being ioved back by grasping the frame butA to prevent its being moved forward. This is brought about by pivoting the clutch 7i at a point forward of its center. ln other words, the weight is prevented fronti pressing the follower against the labels at the. time at which a label is to be taken out At the opposite point all resistance is removed and the whole pile of labels is pulled forward by the weight. Supported a cross-piece on the bars 32 is a` iiXed plate 75 for engaging the top of the follower beam opposite `the clutch 74. lt is adjustably mounted on two screws 7 6.

Pivotally mounted on a cross rod which is supported by the longitudinal rails 3Q there is a. depending lever 77 which has at the bottom a T-shaped guard plate 78 for engaging the top and front of the labels in the holder as indicatedin Fig. 1S. This hangs by gravity in the position shown therein. lt has a forwardly projecting arm 79 which engages the bottom of one of the side rails so that it cannot swing forward beyond a certain limit but it can swing backwardly with the labels.

One of the fea-tures of this machine is the means for gumming the labels in the holder and withdrawing them therefrom one by one. For this purpose a gum box 80 is shown mounted on the frame l0. This gum box may be of any desired lrind in general, but is intended to be sealedl at the top when it is filled, and is provided at the bottom with an outlet valve casing 8l for receiving a valve 82. p This valve is of a modified truncated conical. shape. It is lcirc'ular at each end, one of the circular ends being of larger diameter than the other, but one element of the modified cone at thel bottom is horizontal while ythe aXis is on an angle to the horizontal half as large as the angle which the opposite element makes with the horizontal.

This valve is located in the kvalve casing Si which has the same external shapefand the casing is provided kwith a passage 83 i oaenino' from the inside of the oum box t: 23

to the exterior of the casing through the' bottom thereof for discharge of the gum. The valve is provided with a similar passage 84- at the bottom which, when the valve :is wide open, registers with the passage S3. The valve can be turned so as to decrease the outlet for the gum as shown in Fig. 1S.

The gum box has a trough 85 which receives the gum and will hold the gum at the level of the top of the effective outlet S-Sf because, no air being admitted into the top of the gum boi;7 the gum cannot flow out of the outlet unless the level of. it in the trough is .depressed enough rto allow air to enter over the top ofthe gum in the trough and through the valve. n

Through the front end of the trough eX tends the main shaft 1:2- mounted inbearings on the frame7 these hearings having removable caps 87 preferably. -This shaftsupports a gum roll 88. This gum roll is so located that thel external surface will extend below the surface of the gum in the trough 85, no matter how little gum it may contain. lion of the arrow in Fig. 18 and a scraper S9 is provided on the rear having a surface for scraping any surplus gum from the gum roll. This is mounted on a frame 90 pivoted on studs 91 and adjusted by two screws 92 screwing into the top of two arms 93 on the frame, and normally holds the scraper against the roll. The screws are mounted in lugs 94 on the frame. Nuts 95 are shown for adjusting the height of the frame 90 on which the scraper is mount ed. The screws are adjusted by turning them by means of their heads and check nuts are shown for holding the adjustment. The purpose of the gum roll is to take the gum out of the trough S5 and present it to the surface of a label gumming and carrying member 100. This cylinder is provided with circumferential grooves lOl preferably spaced equally apart longitudinally so as to provide spared surfaces to take gum from the gum roll, and it also takes the labels out of the label holder itself. The gum roll 88 may be driven fromV any ydesired source of power but is shown as mounted on themain shaft l2 which is pro- This roll is rotated in the direcvided with a gear 97ineshing with a double screw eyes 103. v'l`husth'e shafts 86and 96 can be removed .readily and quickly fixedy in position.

1 Meshing with the gear 90 is asmall gear 105 `on a cross shaft 106. This shaft has a Contact or pressure roll T on it comprising a series of discsor circular projections 108 which together constitute an interrupted cylindrical surface having circumferential grooves between the discs alternati ing with the grooves in the gumming memberr100, tor a purpose to be described. On the other end of the shaft 106 is a gear 109 meshing with a gear 110 on a short shaft 111 supported in bearings on one side ot the trame and extending through it. On the outer end of this shaft is a gear 112 meshing with al smaller gear 113 on a shaft 114 extending across the machine and provided with a guide roll made up of discs 115 spaced apart and also each one ot' them spaced so as to extend between an adjacent pair of discs 108. These two rolls are parn allel with each other and close to each other as indicated by the 'fact that the discs ot one projert between the discs of the other.`

The gear 110 also meshes with a gear 116 on a shaft 117 which carries a pressure roll 118. The three rolls 108, 115 and 118 are located halt way between the two sides et the machine and they all rotate positively with the gumming cylinder 100. The pressure roll 118 is provided with a surface et soft rubber, as for example, sponge rubber,

and its ottico is to press the label on the ar-l ticle B to be labelled under a light pressure and yet firmly hold it in contact therewith as soon as the label is in Contact with the roll.

Mounted on one of the side trames there are three pins 120 and on the opposite sidetrame there aretwo pins 121. These pins project inwardly toward each other and constitute supports for the opposite ends oit a transverse bar 122 which carries a comb 123. The `pins 120 are so located with spect to each other as to receive the L-shaped end ot the cross bar 122 between them. This end rests between two of the pins and over one ot them. Its rear sur- 'tace projects back in Contact with the center one and it just tits under the third one which is at the top. On the other end the two pins 121 are located like the lirst two pins 120 mentioned above. Thus the bar is provided with a stop at the rear on both ends and with a support under it.` In locating it in position it is swung in at the right as shown in Fig. `18'and then the lett hand end `is placed in position. j This iXes it and prevents its accidentaldislodgment although it is readily detachable at all` times. Thel comb 123 has teeth spaced like the grooves in the gumlming cylinder and it located so as tov project into the grooves.

These 'teeth are concave on their forward side so that the labels on 'the ygiunmin'g cylinder 100 will be forced from the surtace thereof bythe stationary `comb and brought down away trein it along the concave surface et the teeth et the comb 123 into contact with the receptacle tobe labelled. j

The grooves on" the guinining cylinder 100 are cleaned by a cleaner 125 detachably mounted on legs 126 projectinginwardly from the iframe.` This groove cleaner is provided with projecting teeth 127 adapted to extend` into they grooves andtalre the surplus glue outof them as the surface of the cylinder rotates past them. It located right over the gum roll 88 so that any gum or glue dripping from it will drop upon its surface and be used over again.

I have found inpractice that the application of the label to certain kinds ot receptacles, as for example bottles,` by such methods as this sometimes results in the elevation ot the rear end ot the receptacle v"when it irst comes in cont-act with the pressure roll as 118. This is particularly true in travelling at high speed and in that case is apt to cause considerable di'lliculty. For the purpose of avoiding that, I have provided an anti-jump roll 130. Thisis mounted on arms 131 projecting downwardly from a cross bar 132 which extends across the machinel and is pivoted on studs 133. There is an upwardly estending arm 134 from the cross bar which is normally drawn back against a fixed stop or stud 135 by a spring 136. This yieldingly presses the anti-jump roll 130 against the article to be labelled at a point whichprevents' `its jumping up when it rst comes into contact with the pressure roll 118. It will be understood from the above that this article B is intended to travel under-these rolls as will be explained later. i I It will bef seen, therefore, that `the label is fed forward by providing the constantly rotating gum cylinder tor engaging the rear surface ot the label while the label holder is moving toward it at high speed and immediately' shitting the labelholder back from f Contact with the cylinder. Thus, thepres` sure on the labels is entirely removed Jfrom the label which engages the cylinder and thus the adhesiveness of the glue on the gum roll draws the Y lirst label away from the others. In this way the uncertainty otre- 'moving a label from thelabel holder is practically eliminated and the danger ot taking out two` labels is also avoided. The shifting back of the label holder suddenly leaves the labels `in a comparatively loose condition in lll) the front of the holder'but their upper ends are prevented' from moving forward relatively tothe label holder4 itself. Immediately after' the llabel:` is removed from Jthe side of the label and steer its forward edge upwardly into contact with the discs of the contact roll 108. These discs force the label into contact with the gumming cylinder so that it will therefore pass around with that cylinder and the whole length of its rear surface will be ygummed. The contact roll, like the other rolls, is rotated positively and this makes the feed of the label positive so that it canv be kept in timel with the feed of anarticle B below:

Passing from the contact roll on the surface of the gumming cylinder 100 thev forward edge of the label is separated from' the 2 latter by the comb 123 and forced to travel" along: its concave surface as indicated in Fig. 18. The action of the gum surface 100 helps force theforward edge of the label forward into contact with the bottle or other` article B. This, as will be described below, is travelling forward in the direction ofthe arrow while the pressure roll 118 is rotating in the saniesurface direction and at the same surface speed. This rolls the label on .the article B as thelatter passes through the machine. The teeth of the comb touch only the ungummed. parts of the label.

For the purpose of feeding the bottles B or other articles to be labelled, l have provided the following mechanism. On the main driving shaft 12 gear 97 drives a train of gearing 141 that. in turn, drives a gear 142 on a shaft 143. This vshaft is located at the feeding-in end of thev frame 10 and is supported by a pair of bushings 144 and 145 carried by the frame and in turn constituting the pivotal. supports for the yoke 29 as well as the arm 27 These bushings are supported in bearings on the frame 10 and held in position by set screws 146 so as to support these heavy parts-'above mentioned and also support the shaft 143 which otherwise"would be required to carry the heavy weight of the frame for moving the label holder.

On the shaft 143 is located centrally a sprocket wheel 147 over: which passes a sprocket conveyor chain 148 having projections 149. which are adapted to engage the rear ends of the bottles B or other receptacles .to be labelled and push them along.. This l chain is supported at the other 'endby a similar sprocket "wheel von an idlerl shaft 150. Also. fixed on the-shaft 143 isa driving sprocket' wheel or pulley 151"1ope'ratinga forations 168.

sprocket chain or lbe'lt 152 which passes over a similarfwheel or pulley 153 on the shaft and drives it positively. The top strand of the chain 148 is arranged so it is taut and it is also arranged preferably in` a nearly horizontal position. It is adjustable up `and down to take care vof thick and thin articles or-bottles. The shaft 150 is mounted on the extreme end of a supporting fram/e 156 eX- tending along besidet-he upper active strand of the conveyor cha-in 148 and constituting a platform for vsupporting the bottles or receptacles as they slide along propelled by the chain 148. This frame or platform is provided with a longitudinal slot through which the chain and its projections 149 project. This platform 156 is pivotally supported at the intake end of the machine by .means of enlargements or hubs with which.

it is .provided bearing on the inner ends of' the bushings 144 and 145.

The platform is also supported and pressed upward yieldingly at the opposite end of the machine. For this purpose I have provided a cross bar 158 lon the frame and constituting part of it. Through this passes a screw 159 arranged verticallyand having a hand wheel. 160 at the bottom forfoperating it. At the upper end this screw bears in `conical concave bottom 161 of a metal plate 162. The convex side of the cone centers a spring 1637 the upper end of which is centered in a recess 164 carried in the bottom of the platform 156. This platform has cross pins 165 for supporting the ends of the metal plate 162. Thus, the platform is yieldingly supported at this end, the other end being positively pivoted.

On this platform vare shown side projec tions 167 provided with several small per- Two pairs of these projections are shown all in the plane of the platform. Intov these perforations are adaptu ed to extend pins 169 onr a pair of guide bars 170. The perforations are at different distances from the chain 148 and the guide bars therefore can be set at dilfer ent distances apart and are usually set at equal distances from the chain. They guide the 'articles to be labelled andprevent their getting out of central position.v

By means of legs or projections-172 eX- tending from a feeding-in frame 173 this frame is' pivotally mounted on the bushings 144. It is provided with a `pivoted longitudinally adjustable -rod174 which is adapted to lset into a notch i-n a cross bar 175 on the legs 11 of the frame. This frame is arrangedy for the purpose of facilitating the feeding ofthe articles to be labelled into position for the conveyor chain 148 to carry them through the machine. For this purpose a pair of belts 176 run'along the surface of this frame'gor platform' 'over driving. pulleys 1771011 the'shaft 143 and lnastreeft idler jnilleys 118 on an idle shaft 179 supported at the outer end ol the frauic 178. For the purpose of guiding the bottles l or other articles to be labelled down this traino into enz/agement with the conveyor .ln-.8, lf have shown a 'oar 180 pivoted to the frame 1,78 at a point 181. 'ihis har has i slot 182 concentric Withits pivot and a thumb sci-eu* 1U?) passing); through the slot into4 the frame 1??) for securing the bar in an): adjustable position. Also pivoted at 181 is a guide 184 having a spring 185 connecting it with the bar 180 and normally oscillating theV free end of the guide inwardly toward the belts 176. r1`his forms an adjustable guide with a surface for directing the articles downwardly on the conveyor in central position said surface being` yielding to prevent crushing the bottles.

@n the other side of the belts 176 I have provided another swinging bar 190 pivoted at 191 on the frame 173. This has a guide 194 movably connected with it by means of an adjusting thumb screw 193 passing through a slotted adjusting member 192. This adjusting member is thus capable of being` adjusted to any desired position transversely With respect to the bar 190. 1t is pivotally connected by means of a bracket 195 with the guide 194 and by a link 196 with the pivot stud 191. inl order to provide a substantially parallel motion7 parallel link 19'? is provided pivoted to the bar 190 and to a corresponding bracket on the bach of the guide 194. A spring 198 norinally` swings the bar 190 back as far as possible. @n the gear 142 is a hub 199 haring a roller 200. This roller engages a cam'surface 201 on the end of thebar 190 and forces outthe bar and its guide 194 in opposition to the spring 198 once during each rotation of the shaftf148. The object of this, shown in the dotted lines in Fig. 25, is to force the bottle B against th'eyielding guide 184 hard enough to hold .the bottle back and prevent its discharge of the conveyor chain 148. There is one projection 149 on the conveyor chain in each `space equal to or greater than the circumference of the sprocket Wheel 148 so the conveyor chain takes a bottle for each revolution. Therefore, the roller 200 can be spaced in such position on the shaft 148 that the bottle Will be held back until just time for one of the projections 149 to of continuous grooves around it, it is provided with a plurality of segmental plates 298. each one having alternate groow-is 204 and cylindrical surfaces 205. rlhese plates are fixed vin position by screws `206 and the spaces on each side of them circumferentially are below the level or inside the circle of the surfaces 295. In this construction a label is taken on each one of these surfaces instead. of having the whole circinnference for that purpose. This uses less glue than in the other case and is particularly adapted for those machines'that are to be used always for labels of the same length. Between this cylinder and the gum roll 88 l have shown contact With both. This ensures feed of gum `even after the surfaces or bearings are much Worn.

Although l have specihed the operation of severa parts in connection with the detailed description thereof, l will describe the oper ation of the Whole machine. It will be un derstood that the glue pot 8O is filled with liquid `glue or other adhesive and that the machine is driven at a high rate of speed.v thisfbeing possible on account of the fact that the most of the vparts are rotary and especially the heavy ones.y The rotation of the main shaft 12 carries with it, of course. the two cams 14 and 15 and as stated above `their rotation positively reciprocates the yoke 18 carrying With it the upper ends of theilevers v2O and 27 and also carrying` With it directly the yoke 28. This yoke through its connections oscillates with it the cor-` responding yoke 29 at the other end of the machine. The action of this oscillating m0- tion is to carry the label. frame 33 ,back and forth positively moving in a horizontal path. The labels L .in the label holder between the side frames 37 are pressed forward by the follower 5G actuated by the Weight 54. This forward pressure is re-k moved by the action of `the clutch but the follower remainsv in place. The label guard 66 is held up against the front of the labels as shown in full lines in. 18 bythe action ofthe canr61 until such time as the label holder has moved almost .toits limiting position shown in dotted lines in Fig. 18. At this, time the action of the stationary cam slot 62 on the `lever 67 brings the label guard down away from the label into the dotted line position in that figure where it is out of the Way. The top guard 78 is positively held in the position shown in dotted lines in that ligure so that the labels cannot be dislodged at the top. New, when the label holder comes into its dottedline position suddenly, on account of the shape of the'cams 14 and 15. the rotating gumining cylinder applies its glue to the rear sur face of the first label and instantly brings ice the labeldown edgewise out. ot the label holder on account ot its rotation. There is only a small lip 104 at the bottom and ibi top guard 78 does not interposc any resistance. The labels are loose at thisl time.y therefore, the label passes along down with the surtace of the gumining cylinder 100A moving down away from the drum materially by the discs constituting the guide roll 115. Therefore, the label will be moved along circiunferentially so that its forward edge willvmove in between the gunnning cylinder 100 and the contact roll 10S. This presses the label rmly against the surface of the drum and insures a full coating` ot glue upon the label put on in spaced stripes. Further travel ot the label results in its be- Aing combed od the gumming cylinder 100 respect to the operations of the .label holder,

and the pressure roll 118. The surfacey speed oit the latter is substantially the same as that of the pressure roll. The jumping up of the rear end of the bottle at this time is prevented by the anti-jump roll 139 as stated above.

The feeding ot the bottles or other reccptacles has also been described but they are put in by hand or machine on the 'feeding belts or tapes 176. Periodically the guide 194. is forced over as shown in Fig.l 25 to grip the bottle againstthe yielding guide 184. This holds the bottle back until the proper projection 149 is in position to engage its rear end and then it is released by the'withdrawal of the guide194 due to the cam 201 and the spring 198. The bottle drops on the conveyor gently just as the projection 149 comes around into position to engage it and the conveyor carries it up on an incline at the same rate as that at which the surfaces of the rolls 118, 108 and the guinming cylinder 100 are travelling. The roll 115 travels at va l,f reater surface speed.

In this way a machine is provided which can be rotated at a high'speed, attended by comparatively unskilled laborers, fed with bottles or receptacles either by hand or mechanically,-. and. operated with a high degrec of efficiency and a small percentage of stops and breaks, 'for the purpose ot labeling` bottles, cans, jars, paste-board receptacles, and cartons, and in fact, anything which is to be labelled in large quantities. As has been stated throughout the. specification, it will be understood that the parts are designed tor high speed and constant operi.-

tion and that they are of such a nature as.

to permit ot all desired fiexibility of operation without constant attention by a skilled mechanic.
